GLASS-BLOWING MACHINE.

Application filed December I To all whom it may concern:

-Be it known that I, ROBERTIP. Fnis'r; a citizen of the United States of America, residing in Bridgeton, in .the county of Cumberland, in the State of New Jersey,

have invented a certain new and useful Improvement in Glass-Blowing Machines, of which the following isa true andexact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to machinery for blowing glass and particularly to that part of the mechanism through which the blast is introduced into the glass blank to be blown. The. object of my invention is to provide for a better and more'perfect formation of the neck of a bottle or similar object being formed in the machine.

Primarily my invention consists in the use of a die like. blast nozzle which is forced into the neck of the blank which of course is held in a suitable mold and retained therein during the blowing of the glass. Preferably, and this is an important feature of my invention,

line 22'of Fig. 1'.- v Fig 3, is a view showing the bottom, of the-actuating spindle, its valve, the die nozzle. and parts connected therewith, showing the partsin the position they occupy when the spindle is raised out of operative position. Fig. 4, is a perspective view'of a 3 5 bottle'such as is formed in the mold illustrated. Fig. 5,

isa plan view of the machine, and Fig; 6, a side elevation of a modified form of machine also embodying the leading ieatures'of my invention.

A, indicates the stationary table or base of the ma- 40 chine; B, a standard supported on said table; 0, a rotatable table moving on the standard B, or about the same.

This table, as shown, is provided with three mold receiving pockets C, C, C, provided withadjusting and clamping bolts, as indicated at C and the table also has secured on its upper face and symmetrically disposed with reference to the mold pockets, the lugs C G etc.

D, D, D, are molds which, as shown, are longitudinally divided into sections hinged together at D, and provided with handles as shown at D D These molds, as shown-in Fig. 2, are formed with cavities corresponding in form to the bottle or other object to be formed therein, the neck portion being adapted .to form the neck of the bottle and also provided with a seat, -as

indicated at D Specification of Letters Patent.

Patented Aug. 6,1907. 904. Serial at. 235,959.

" The bottle is shown in Figs 2 and 4, at E, the usual neck and rim being indicated at E I Between each pair of lugs C is secured a pivot pin F, on which is hinged a latch lever F, having an upwardly extending handle, as indicated at F The latch levers are arranged to engage successively in the latch detent H, of the stationary rim H, having an inclined Surface H overwhich the latch levers ride to enter the cavities H. This latching device in combination with a mold carrying table forms in part the subject matter of my application for Letters Patent filed December 8th, 1904, Serial Number 235,960.

G, is a bracket which is secured to the standard B, preferably by a clamp as indicated at G, so that the bracket can be shifted in position 011 the standard. The bracket carries a guideway G and also supports a pivot pin G to which is secured the yoke lever H, the outer end H, of which is secured a counterweight H while the inner end is provided with a handle as indi-- connecting rods I, I, the upper ends of which are connected to pivot pins 1, I, on the crosshead J, which crosshead is secured to the upper threaded end K, of a which normally rests a valve N, with a depending" spindle N. p

O, is'a' collar or head of acasing Q, tl 2 said collar being provided with balls or other devices forengaging with thethreads K ,of the spindle K, and the casing Q, having aperforated bottom Q, and an annular shoulder' Q extending .below this bottom and preferably provided with ball bearings, as indicated at It, R. I To theinside of the collar Q, is secured the die blast nozzle indicated at S.

In operation, the table 0, is rotated until one of the molds, which has already been provided with a blank, the preferable form of which is indicated in dotted lines at E, Fig. 2, is brought into position immediately below the spindle K, in which position the table is arrested by the engagement of alatch lever F, with a latch detent H; the spindle is in elevated position, and the casing Q, and valve M, occupy the relative positions indicated in Fig. 3, the operator then presses down the handle lever H whichthrough the connecting rods 1, 1, draws the spindle K, downward, forcing the blast nozzle S, into the mouth of the blank and bringing the collaqQ down upon the bearing D of the mold, as these parts are shown in Fig. 2. The further continued downward movement or the spindle K, through its screw connection with the casing Q, then rotates the said casing and the nozzle S, and while this operation beneath the spindle.-

"lieve-themechanism illustrated and above described is rotation is going onthe valve box M, and the valve N, are moved downward in the casing Q, until near the end of the downward movenient the valve spindle N, comes in contact with the perforated bottom Q, of the casing, opening'the valve and admitting the air to and through the nozzle S, and into the blank which is then j to'r, then taking hold oi the handle F oi the engaged hlever lifts the lever out of engagementand rotates the'table until the next succeeding mold comes into I have already mentioned that the latching mechan ism shown is in, part the subject matter of my above mentioned co pending application end this is also true of the movable bracket G, as applied to any molding apparatusi I would-also mention liere that while I bethat best adapted for the embodiment and ,utilization I of my invention, it is capable of modification and j changeiwith regard to the special arrangement-oi the valve for admitting air and the mechanism for rotating the blast nozzle, arid I Wish to be clearly understood as asserting that my inventions are in no wise dependent on the illustrated'mechanism, except Where this mechanism i s'spe cifical-ly referred to and called for in the '1 claimsfi p V V 6 I have'illustrated one practicable modifica-:

In. i g

y invention, the machine being substantially s that already described ei ccept that inst ead I in 'a'threaded spindle K, the spindle in this case, which of-c'oiirse supports thedie n ozzle is rotated and 'throughjit/the nozzle-rotated by means of ahand wheel '1, secured to the spindle, as shown.

' ,Havihg now'described my invention, what I claim as new and desire to secure by Letters Patent is 1.111 a glass blowing machine of the class described,

the combination with a mold adapted to receive the blank to be'blown, of a longitudinally and rotatably movable die blowing nozzle adapted to enter the neck of the blank and also to seat itself on the top of the mold above the blank and means for rotating said in operative position.

12.111 aglassfblowing machine of'the class described,

- tudinally movable spindle having a steep threads formed on its exterior,

rest against the top of the threaded spindle longitudinally therein, a casing die nozzle when so seated and the combination, with arnold adapted to receive the blank to be blown, of a die blowing nozzle adapted to enter the neck of theblank and also'to seat itself on the top of the mold above the blank, and means for depressing and elevating rhe nirnozzle to engage and disengage the mold and the glass therein, said means being connected with the nozzle so as to rotate it when its vertical motion is arrested.
